Fetch the full message history of a single conversation by id. Returns each message with direction (incoming/outgoing), timestamp, and body.
AI agents call get_conversation_messages to retrieve information from Hostaway-mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical conversation data without side effects. Fetching message history is a query operation that does not create, modify, delete, or execute any actions. The blast radius of misuse is limited to unauthorized access to conversation content, which is a read-based confidentiality risk, not an operational or destructive one.
From the tool's definition Tool description states "Fetch the full message history" and server is described as providing "read-only tools". The action is purely retrieval with no modification or execution.
Attacks that exploit this kind of access
Fetch the full message history of a single conversation by id. Returns each message with direction (incoming/outgoing), timestamp, and body. It is categorised as a Read tool in the Hostaway-mcp MCP Server, which means it retrieves data without modifying state.
Register the Hostaway- MCP server in PolicyLayer and add a rule for get_conversation_messages: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Hostaway-mcp. Nothing to install.
get_conversation_messages is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_conversation_messages rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_conversation_messages. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_conversation_messages is provided by the Hostaway- MCP server (prosperkartik/hostaway-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
